"I can't believe it's been a year, it's just shocking," says Sheryl Crow as she muses over how Prince's death influenced her songwriting.
He and Crow had recorded and performed together several times, but she says:"I had lost touch with him through the last 10 or 15 years.
"I hadn't seen him, and you have that moment where you think 'I wish I'd stayed in touch, I wish I'd been a better friend.'"
Prince was found dead last April at his Paisley Park home after taking an accidental overdose of the painkiller fentanyl.
"When he passed, they started showing all this old footage and I started hearing all that old music again that I'd loved and meant so much to me," Crow says.
"What it made me do was, while I was in the studio and while I was writing, his passing in some way made me feel like everything outside of love, caring and compassion seemed worthless.
"And this was at time when our US election campaign was going on and it was just so vitriolic, and you see the light go out on this incredible talent, and it did make me feel like I want to make music that matters to me. It brought back the urgency."
Crow is speaking to the BBC in London ahead of a series of live shows in support of her 10th album Be Myself.
It's striking during the press interviews she's doing that there is no big entourage and no PR people in the room. She's keen to point out she likes to devote her full attention to living in the moment and, crucially, not be on her phone all the time.
"Smartphones are banned in my house!" she laughs. "I know I'm not going to look back on my life with my kids and think 'I wish I had been on my phone more'," she says.
The huge technological shift is one of the biggest societal changes there's been since she first rose to prominence in the pre-smartphone age with her 1994 breakthrough single All I Wanna Do.
"There's a huge problem and I think it's really informing civilisation about who we're becoming. We're all attached to these gadgets which are supposed to keep us connected, and yet they're creating a disconnect."
She admits that while she's not being entirely serious about banning phones in the family home completely, she has gone through something of a technology detox recently: "I've just made a pact with myself and I'm much happier.
"I pick my phone up once a day and check it, but it's always on silent. If you detox from your phone you'll realise how much of your day is spent looking to see what you're missing, and what you're missing is your life."
